Axon Data Schema Fields
The following sections describe the intended purpose for each of the fields within the Axon Data Schema.
Not all the Data Schema fields are available for assignment through Policy Builder. These fields are assigned by the Axon system as part of normal message processing. Fields that are "mappable" can be assigned within Policy Builder, whereas fields that aren't are set by Axon and cannot be changed.
Origin, Target, and Observer Fields
Account Name vs. ID vs. Email vs. UPN
Some log sources and their messages produce confusing results. There are several sources that use email addresses as their account names and others that use some type of ID. Axon’s approach to these attributes is to store them in separate fields based on their context.
User Principal Names (UPNs) are generally unique to Microsoft products. They are used in both the Windows Operating Systems and in Microsoft Azure. These should not be confused with email addresses or Account Names.
The Email fields are only relevant when the messages are describing email-related traffic. This could be message tracking, message inspection, or some other controls specifically for the email message transportation, inspection, or management contexts.
The ID field is meant to be used in conjunction with the Name field and not on its own. An Account ID is some internal identifier that the producing log source uses to track account objects. A common example is the SID value in Windows environments.
The Name field is the most used field. When a message describes an account object, it most frequently references the Name attribute. This could take many shapes, including that of an email address.
